there are already many posts about this Subject; however, I think what happened to me this morning (7/1/2016) if a different situation.  My @Hotmail.com email at Windows Live Mail has been working just fine.  I was part way through the specified migration process to get ready for the deactivation of Windows Live Mail since it will soon no longer connect to the new version of Outlook.com.  The migration has been going well, and I adjust the folders containing email in Windows Live Mail, and then synchronize with Outlook.com, the new folders containing the emails are showing up just fine on Outlook.com.  However, part way through the process this morning I started to get the "Unable to send or receive messages for the Hotmail account."  Ever since I've been getting that error message, any of the new folders I've been creating in Windows Live Mail no longer sync and show up in Outlook.com.  The Windows Live Mail team said they'd be starting to deactive the Windows Live Mail accounts, but I need my account reinstated for a few more hours so I can finish my migration/synchronization.  This is an issue with deactivating the "https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx" service.  Can someone at Microsoft please reinstate my Windows Live Mail account for a few more hours?  HELP
